Rapid Discovery and Evaluation of Thermal and Environmentally Protective Coatings for Metals
Jeffery A. Aguiar, Ph.D.
With increasing speed, degrees of maneuverability, and expected range, current and future air vehicle systems, specifically at leading edges, stagnation points, and nose tips pose severe and growing challenges to conventional high-temperature materials. Models over notional trajectories for current and future air and space vehicles suggest at least a greater than an order of magnitude improvement in derived protection levels are required to enable powered next generation airbreathers and glide bodies. The derived protection level includes several considerations, such as resistance to high-temperature oxidation, structural stability, ballistic impacts, and thermal management to manage heat flux gradients at leading edges, stagnation points, and nose tips. Focused efforts on the discovery, development and implementation of materials and related coating technologies are thereby fundamental to sustained and rapid innovation in air and space access vehicles.
Discovery, demonstration, and integration of ultra-high thermal and environmental barrier coatings for refractory materials, including titanium and ultra high temperature capable niobium-based C103 alloy, represents some of the pressing needs for the ultimate control and survivability of systems traveling at the immense speeds endemic to sustained hypersonic flight in air. Given the focus on advancing technical readiness and fielding of new and upgradeable systems several fundamental materials issues remain. Amongst the use of manufacturing methods for refractory materials, coating development and testing provides the enabler for operation and extended use, including withstanding heat fluxes ranging above 100 W/cm2, highly dynamic and static loads of operation, ultra high temperatures and sustained phase equilibria above 2200 °F to nearly 4000°F. At Lockheed Martin, given the precedence for coating technologies, we are rapidly developing and testing novel chemistries, topologies, physics-based modeling, to evaluate and provide novel thermal and environmental management, while maintaining predictable phases, mechanical and physical properties to enable and extend the capabilities in current and future air vehicles.
We plan to present and discuss on our ongoing work across Lockheed Martin to (i) identify, (ii) develop, (iii) manufacture, and (iii) test candidate coatings that exhibit a blend of high-temperature resilience and behavior for use on metals. Finally, we plan to conclude with points of collaboration and potential partnerships focused on the development and innovation surrounding advancing the current state of the art coatings for future air vehicles.

Chemical Vapor Deposition Coatings
Erin Westbrook, erin.e.westbrook@lmco.com
Chemical Vapor Deposition (CVD) is a method to deposit solid films onto heated substrates by leveraging chemical reactions in which the reactants are in the gaseous state. CVD coatings at Lockheed Martin provide thermal protection and corrosion resistance to components subject to the most extreme thermal environments. These include leading edges, nozzle throats, pintles, inlets, and nozzles; this technology is also used for deposition of optical coating systems in components like nose tips. Lockheed Martin’s recent CVD coatings work targets ultra-high temperature (UHT) leading edge or inlet applications, depositing on carbon-carbon, carbon-silicon carbide, and silicon carbide wafers. Future work may expand to coat larger parts and metal components such as titanium; this facilitates lighter weight, more traditionally designed structures’ survival in extreme temperatures > 2000F. Recent investment in a state-of-the-art custom CVD reactor at the LM Rosamond site facilitates a fivefold increase in throughput for components like pintles and a highly tailorable coating zone with chemical doping capability. This reactor is scheduled for commissioning in August of 2024.
Robotic Needling of Ceramic Matrix Composites
Tommaso Giovannini, tommaso.giovannini@lmco.com
Ceramic Matrix Composites (CMCs) are a class of materials which consist of ceramic fibers embedded in a ceramic matrix. Their high-temperature mechanical strength, toughness, and good shape stability, make them well suited to modern-day hypersonic applications. Because most of the strength in CMCs is provided by the fibers, conventional 2D layup processes make them susceptible to delamination and have limited their structural applications. Fabricating components near-net-shape to reduce part machining costs, is also problematic due to poor drape properties of the fiber plies. Robotic needling (2.5D processing) is a process which enables the production of near-net-shape CMC components with improved interlaminar properties. By pushing barbed needles through stacked ply layers, fiber is transported in the through-thickness direction (z-fibers) providing initial consolidation of the plies. The z-fibers enable the fabrication of complex contoured shapes and lead to significant improvements in the ILT/ILS strength of finished CMC components.

Aeroshell Scale-up with Manufacturing Demonstration Articles (MDA)
Brian Zuchowski
Challenges of extreme high-speed environments continue to demand more capable high temperature/high strength material systems for aeroshell structure, as well as be poised to meet future acquisition rates projected by the Department of Defense (DoD). In support of 2.5D Carbon-Carbon (C-C) and Ceramic Matrix Composite (CMC) material integration into aeroshell structure development, an aeroshell Manufacturing Demonstration Article (MDA) 1.0 has been developed for relevant design type structural aeroshell manufacturing and processing. 2.5D structure refers to a material system with the inclusion of strength reinforcement in the through-thickness direction. The 2024 MDA 1.5 fabrication effort is demonstrating manufacturing capability and scale-up and is leveraging the strength and stiffness advantages of the in-development 2.5D material system to reduce structural risk for future platforms based on higher interlaminar strength at high temperature capability. In addition, robotic needling of the aeroshell skin laminate has been demonstrated. This manufacturing technology demonstration is a part of the Affordable Capacity for Hypersonic Aeroshells (ACHA) and LM Aeronautics IRAD funded material development efforts to demonstrate aeroshell structure manufacture and progression to rate production capability in parallel with capturing aeroshell Material and Processes Intellectual Property (IP) in CMC structure processing. This presentation shall cover the background of the MDA design, development progression, and the current status of the MDA 1.0 and MDA 1.5 efforts along with scheduled structural hardware processing.

ECHOS: Integrating a Multi-Target Random Finite Set Tracker into a Multi-ship Passive RF Geolocation Processing Pipeline
Daniel Lundberg, PhD, daniel.p.lundberg@lmco.com
Prior work under the ECHOS IRAD developed a passive geolocation pipeline for low-SwAP platforms that included signal detection, classification and geolocation. The existing geolocation solution was limited to a single stationary target on the ground. This work extends the processing pipeline to handle multiple moving targets by integrating a Random Finite Set Tracker based on the pytrack track filters developed by LM ATL. These track filters inherently handle multiple measurement sources and modes, and have favorable computationally scaling in dense scenes compared to the state of the art. This tracker is integrated into the ECHOS suite of services as a UCI Team Service. Single/multi-ship Angle of Arrival and / or multi-ship Time Difference of Arrival measurements are used to produce multiple target tracks. The processing architecture, deployment use cases, and example results will be shown. Implications for the training of autonomous AI agents using passive geolocation will be discussed.

Project Gamma: Generative Design and Analysis of Aerospace Structures
Ben Gajus, benjamin.gajus@lmco.com
Generative design is a paradigm shift in how Lockheed Martin executes its engineering workflow and results in two primary benefits. The first of which is the streamlining of the design process by reducing handoffs between users and software resulting in a reduction in overall cycle times. The second principal benefit is the optimization of design solutions based on objectives. This is accomplished by utilizing physics-based modeling early in the design process and simplifying user access to the power behind advanced solvers. When combined, products may see reduced costs, faster time to qualification, reduced weight and complexity, as well as increased cross-functional engagement without compromising validation and verification. The Project Gamma team, as part of the Lockheed Martin Advanced Development Programs (ADP) Star Drive initiative, has been investigating the generative design utilities within Dassault’s 3DX platform and Collier Aerospace’s Hyper-X utility and developing an engineering workflow to assist in understanding and adopting these tools. The team also explores opportunities to automate engineering workflows to increase efficiency and enhance the digital thread. Through this work, the Simulia solvers within the 3DX platform have been verified. As a result, innovative and non-intuitive design solutions have been produced that otherwise may not have been explored and methods of analysis are beginning to be leveraged within the 3DX platform. Compared to traditional design and analysis, the Gamma team is exploring workflows that significantly reduce time across multiple sizes of problems encountered in an aircraft design, from the structural layout of a conceptual configuration to optimization of a matured detail part.
